* **context:** refactor context observer subscription into a new class ([31ad9a5](https://github.com/loopbackio/loopback-next/commit/31ad9a55bbd068cd8e41347fca5caaf0ae5eb6e7))
* **context:** set max listeners to Infinity by default ([0741e3b](https://github.com/loopbackio/loopback-next/commit/0741e3b1293065a04f1ecd9dbda09df074a5dd34))
* **context:** use BindingEvent for binding event listeners ([ae5febc](https://github.com/loopbackio/loopback-next/commit/ae5febc35679f4d77b9970ecc26a71938a1c972e))


### BREAKING CHANGES

* **context:** Context events are now emitted as `ContextEvent` objects
instead of positional arguments. Context listener functions must switch from
the old style to new style as follows:

1. Old style

```ts
ctx.on('bind', (binding, context) => {
// ...
});
```

2. New style

```ts
ctx.on('bind', (event: ContextEvent) => {
// ...
});
```

Or:

```ts
ctx.on('bind', ({binding, context, type}) => {
// ...
});
```

cloned deeply. It's still cloned shallowly.

### Features

* **context:** add type as a generic parameter to `ctx.get()` and friends ([24b217d](https://github.com/loopbackio/loopback-next/commit/24b217d))
* **context:** allow context.find by a filter function ([9b1e26c](https://github.com/loopbackio/loopback-next/commit/9b1e26c))
* **context:** use Readonly to guard immutable values ([871ddef](https://github.com/loopbackio/loopback-next/commit/871ddef))


### BREAKING CHANGES

* **context:** `ctx.get()` and `ctx.getSync()` require a type now.
See the example below for upgrade instructions:

```diff
- const c: MyController = await ctx.get('MyController');
+ const c = await ctx.get<MyController>('MyController');
```

`isPromise` was renamed to `isPromiseLike` and acts as a type guard
for `PromiseLike`, not `Promise`.  When upgrading affected code, you
need to determine whether the code was accepting any Promise
implementation (i.e. `PromiseLike`) or only native Promises. In the
former case, you should use `isPromiseLike` and potentially convert the
userland Promise instance to a native Promise via
`Promise.resolve(promiseLike)`. In the latter case, you can replace
`isPromise(p)` with `p instanceof Promise`.
